If a physician's statement is required, it must identify the particular condition of the patient and include the physician's judgment that:

Air bags pose a special risk to the person with the medical condition, and

The potential harm from the air bag outweighs the potential harm from turning off the air bag and allowing the person's head, neck, or breastbone to hit the steering wheel, dashboard or windshield. Note: Hitting the vehicle interior is likely in a moderate to severe crash, even if the person is using a seat belt.

If the request concerns a child who must ride in the front seat to enable the driver to monitor the child's medical condition, the supporting physician's statement must identify the condition and state that frequent monitoring by the driver is necessary.

The agency will respond in writing, enclosing a copy of an informational brochure, labels to be attached to the vehicle interior for alerting vehicle users about the deactivated air bags, and a form to be filled out and mailed back to NHTSA regarding the deactivation.
